Case Study: Major US Specialty Steel Producer avoids major gearbox damage and downtime with SymphonyAI

Analyst detects bearing failure from 2,300 miles away

Major US Specialty Steel Producer, a large East Coast specialty steel mill, needed to avoid unexpected equipment failures in its rolling operation. The company relied on regular vibration analysis of its 16 critical roll stands, but a sudden gearbox bearing issue threatened to cause serious damage and unplanned downtime. SymphonyAI helped support this condition-monitoring workflow through cloud-based data collection and remote analysis.

Using SymphonyAI’s cloud-connected vibration monitoring and analyst review, the mill uploaded vibration data to a remote expert who quickly identified abnormal “noise” in a planetary gearbox and recommended an immediate shutdown. The bearing had completely failed, but the gears were saved, and the mill rebuilt and swapped the gearbox in just 50 hours. Thanks to SymphonyAI’s solution, total downtime was limited to just eight hours, avoiding major gear damage and likely far longer downtime.
